Abstract

A thermo-forming packaging machine has a machine frame and a cutting station including a complete cutting tool. The thermo-forming packaging machine includes the complete cutting tool being extractable from the machine frame in a direction of production of the packaging machine.

First claim

What is claimed is:

1. A thermo-forming packaging machine comprising:
a machine frame having an upstream end and a downstream end;
a forming station on the machine frame for forming containers in a web-shaped material;
a sealing station on the machine frame for sealing the containers, wherein the sealing station is located downstream of the forming station in a direction of production;
a cutting station located downstream of the sealing station and the downstream end of the machine frame in the direction of production, the cutting station including a complete cutting tool having a cutting tool upper part and a cutting tool lower part, wherein the complete cutting tool is extractable from the thermo-forming packaging machine in the direction of production at the cutting station, wherein the direction of production at the cutting station is the direction of conveyance of the web-shaped material through the cutting station; and
first and second chain guides mounted on the machine frame, each chain guide for guiding a transport chain that transports the web-shaped material in the thermo-forming packaging machine, and each chain guide having a downstream end portion that extends beyond the downstream end of the machine frame into the cutting station in the direction of production at the cutting station.

2. The thermo-forming packaging machine of claim 1 , wherein the cutting tool further comprises multiple guides that are configured to guide movement of at least one of the upper part or lower part of the cutting tool, and the multiple guides of the cutting tool are arranged outside of the transport chain and chain guides.

3. The thermo-forming packaging machine of claim 2 wherein the cutting station further comprises a frame to which the guides of the cutting tool are removably attached, and fixing elements provided on the frame for positioning the complete cutting tool in the cutting station for repeat accuracy.

4. The thermo-forming packaging machine of claim 1 , wherein the first and second chain guides cantilever from the downstream end of the machine frame into the cutting station.
